1Precautions for safety
The manufacturer shall not assume any liability for the damage caused
by not observing the description of this manual.
General
• Carefully read Owner’s Manual before starting the air conditioner.
There are many important things to keep in mind for daily operation.
• Ask for installation to be performed by the dealer or a professional.
Only a Qualified installer (*1) is able to install an air conditioner. If a
non-qualified person installs an air conditioner, it may result in
problems such as fire, electric shock, injury, water leakage, noise and
vibration.
• Do not use any refrigerant different from the one specified for
complement or replacement. Otherwise, abnormally high pressure
may be generated in the refrigeration cycle, which may result in a
failure or explosion of the product or an injury to your body.
• Do not install the air conditioner in a place where the operation sound
of the outdoor unit may cause a disturbance. (Especially at the
boundary line with a neighbor, install the air conditioner while
considering the noise.)
• This appliance is intended to be used by expert or trained users in
shops, in light industry, or for commercial use by lay persons.
Transportation and storage
• To transport the air conditioner, wear shoes with protective toe caps,
protective gloves, and other protective clothing.
• To transport the air conditioner, do not take hold of the bands around
the packing carton. You may injure yourself if the bands should break.
• Before stacking the packing cartons for storage or transportation,
heed the precautions written on the packing cartons. Failure to heed
the precautions may cause the stack to collapse.
• The air conditioner must be transported in stable condition. If any part
of the product broken, contact your dealer.
• When the air conditioner must be transported by hand, carry it by two
or more people.
WARNING
Installation
• Only a Qualified installer (*1) or Qualified service person (*1) is
allowed to carry out the electrical work of the air conditioner. Under
no circumstances must this work be done by an unqualified individual
since failure to carry out the work properly may result in electric
shocks and/or electrical leaks.
• After the installation work has been completed, have the installer
explain about the circuit breaker positions. In the event that trouble
has occurred in the air conditioner, set the circuit breaker to the OFF
position, and contact a service person.
• If the unit is installed in a small room, take appropriate measures to
prevent the refrigerant from exceeding the limit concentration even if
it leaks. Consult the dealer from whom you purchased the air
conditioner when you implement the measures. Accumulation of
highly concentrated refrigerant may cause an oxygen deficiency
accident.
• Do not install the air conditioner in a location that may be subject to a
risk of expire to a combustible gas. If a combustible gas leaks and
becomes concentrated around the unit, a fire may occur.
• Use the company-specified products for the separately purchased
parts. Use of non-specified products may result in fire, electric shock,
water leakage or other trouble. Have the installation performed by a
professional.
• Confirm that earthing is performed correctly.
Operation
• Before opening the intake grille of the indoor unit or service panel of
the outdoor unit, set the circuit breaker to the OFF position. Failure to
set the circuit breaker to the OFF position may result in electric
shocks through contact with the interior parts. Only a Qualified
installer (*1) or Qualified service person (*1) is allowed to remove the
intake grille of the indoor unit or service panel of the outdoor unit and
do the work required.
• Inside the air conditioner are high-voltage areas and rotating parts.
Due to the danger of electric shocks or of your fingers or physical
objects becoming trapped in the rotating parts, do not remove service
panel of the outdoor unit. When work involving the removal of these
parts is required, contact a Qualified installer (*1) or a Qualified
service person (*1).
• Do not move or repair any unit by yourself. Since there is high voltage
inside the unit, you may get electric shock when removing the cover
and main unit.
5-EN 6-EN

• Use of a stand more than 50 cm high to clean the filter of the indoor
unit or to carry out other such jobs constitutes working at heights. Due
to the danger of falling off the stand and injuring yourself while
working at heights, this kind of work should not be done by unqualified
individuals. When this kind of work must be carried out, do not do it
yourself but ask a qualified installer or a qualified service person to do
it for you.
• Do not touch the aluminum fin of the outdoor unit. You may injure
yourself if you do so. If the fin must be touched, do not touch it
yourself but contact a qualified installer or a qualified service person.
• Do not climb onto or place objects on top of the outdoor unit. You may
fall or the objects may fall off of the outdoor unit and result in injury.
• Do not place any combustion appliance in a place where it is directly
exposed to the wind of air conditioner, otherwise it may cause
imperfect combustion.
• When the air conditioner is operated with a combustion appliance in
the same place, ventilate the room sufficiently. Poor ventilation
causes oxygen shortage.
• When the air conditioner is used in a closed room, sufficiently
ventilate the room. Poor ventilation causes oxygen shortage.
• Do not expose your body to cool air directly for a long time and do not
cool yourself excessively. Doing so may result in deteriorated
physical condition and ill health.
• Do not insert your finger or a stick into the air intake or discharge.
Doing so may result injury as the fan is rotating at high speed inside
the unit.
• Consult the shop where you purchased the air conditioner if air
conditioning (cooling and heating) is not performed properly as a
refrigerant leakage may be the cause. Confirm the repair details with
a Qualified service person (*1) when the repair includes additional
charging of the refrigerant.
• Stop running the air conditioner and turn off the breaker before
cleaning. Otherwise, injury may result as the fan is rotating at high
speed inside the unit.
Repairs
• When you have noticed that some kind of trouble (such as when a
check display has appeared, there is a smell of burning, abnormal
sounds are heard, the air conditioner fails to cool or heat or water is
leaking) has occurred in the air conditioner, do not touch the air
conditioner yourself but set the circuit breaker to the OFF position,
and contact a qualified service person. Take steps to ensure that the
power will not be turned on (by marking “out of service” near the
circuit breaker, for instance) until qualified service person arrives.
Continuing to use the air conditioner in the abnormal status may
cause mechanical problems to escalate or result in electric shocks,
etc.
• If the fan grille is damaged, do not approach the outdoor unit but set
the circuit breaker to the OFF position, and contact a Qualified service
person (*1) to have the repairs done. Do not set the circuit breaker to
the ON position until the repairs are completed.
• If you have discovered that there is a danger of the indoor unit’s
falling, do not approach the indoor unit but set the circuit breaker to
the OFF position, and contact a Qualified installer (*1) or a Qualified
service person (*1) to refit the unit. Do not set the circuit breaker to
the ON position until the unit has been refitted.
• If there is a danger of the outdoor unit’s toppling over, do not
approach the outdoor unit but set the circuit breaker to the OFF
position, and contact a Qualified installer (*1) or a Qualified service
person (*1) to have the improvements or refitting done. Do not set the
circuit breaker to the ON position until the improvements or refitting is
completed.
• Do not customize the unit. Doing so may result in fire, electric shock
or other trouble.
Relocation
• When the air conditioner is to be relocated, do not relocate it yourself
but contact a Qualified installer (*1) or a Qualified service person (*1).

• The louver automatically closes when running is
stopped.
• In pre-heating mode, the louver points upward.
The swing indication appears on the remote
controller even in pre-heating mode, but the actual
swing starts only after pre-heating is complete.
NOTE
• When stopped, the louver closes automatically.
• The louver automatically becomes horizontal or closed at the start of heating operation, defrosting operation, or when
the set temperature becomes the same as room temperature. If you set the swing or wind direction at this time, the
remote controller display will be the setting, but the louver will not move. When the normal heating operation that
blows warm air is started, the louver will be in the set wind direction.
• When the defrosting operation is performed during heating, the louver automatically closes to reduce the cold air
falling from the indoor unit.
• If the heating operation is performed less than 12 hours after the circuit breaker is turned on when the outside
temperature is low, the louver may automatically close immediately after the start of heating operation to reduce the
loss of cold air.

▼Defrosting operation
If the outdoor unit is frosted during the heating operation,
defrosting starts automatically (for approximately 2 to 10
minutes) to maintain the heating capacity.
• The fans in both indoor and outdoor units will stop during
the defrosting operation.
• During the defrosting operation, the fan of the indoor unit /
outdoor unit stops and the louver of the indoor unit closes.
• During the defrosting operation, the defrosted water will be
drained from the bottom plate of the outdoor unit.
▼Heating capacity
In the heating operation, the heat is absorbed from the
outside and brought into the room. This way of heating is
called heat pump system. When the outside temperature is
too low, it is recommended to use another heating apparatus
in combination with the air conditioner.
▼Protective device
• Stops operation when the air-conditioner is overloaded.
• If the protective device is activated, the unit stops running,
and the operation indicator and check indicator on the
remote controller blink.

• Turn off the circuit breaker and perform a checkup.
Continued running may cause a malfunction.
• Check whether the air filter is installed. If not, the heat
exchanger may be clogged with dust and water leakage
may occur.
During cooling
• The air intake or discharge of the outdoor unit is
clogged.
• Strong wind continuously blows against the discharge of
the outdoor unit.
During heating
• The air filter is clogged with a large amount of dust.
• The air intake or discharge of the indoor unit is clogged.
▼Do not turn off the circuit breaker
• During the air-conditioning season, leave the circuit
breaker turned on, and use the ON / OFF key on the
remote controller.
▼Attention to snowfall and freeze on the
outdoor unit
